DCCD Engineering Corporation engaged AMH to conduct geotechnical engineering assessment for the proposed Cavite-Laguna Expressway (CALAX) – Cavite section. The results of the subsurface investigation for the expressway, ramp, and interchange bridges of the alignment section were evaluated. Soil liquefaction and deep foundation analysis were then carried out for this study. Axial pile capacities were calculated using semi-empirical soil mechanics approach, consistent with the procedures described in the American Association of State Highways and Transportation Officials (AASHTO) 2002. For lateral analysis, a finite-difference method to model soil-structure interaction was adopted.
